Simplified and Pipelined Installation Instruction

1. Enter crosh by CTRL+ALT+T and typing shell to enter shell environment.

2. The following will install usual targets.

   sudo sh ~/Downloads/crouton -r trusty -a amd64 -t unity-desktop,kde-desktop,xiwi,chrome,xorg -e
   

3. Install Chinese Simplified support. First enter chroot by sudo enter-chroot -n trusty.

   sudo apt-get install language-pack-zh-hans
   sudo apt-get install language-pack-gnome-zh-hans
   sudo apt-get install language-pack-kde-zh-hans
   sudo apt-get install libreoffice-l10n-zh-cn
   sudo update-locale LANG="en_US.UTF-8" LANGUAGE="en:en"
   

4. Fix autocomplete

   sudo apt-get install bash-completion
   

   • uncomment completion stuff from /etc/bash.bashrc
   • comment out completion stuff from ~/.bashrc

5. Install i3wm.

   sudo echo "deb http://debian.sur5r.net/i3/ $(lsb_release -c -s) universe" >> /etc/apt/sources.list
   sudo apt-get update
   sudo apt-get --allow-unauthenticated install sur5r-keyring
   sudo apt-get update
   sudo apt-get install i3 i3status i3lock
   echo "exec i3" > ~/.xinitrc
   

   Add alias starti3='sudo enter-chroot -n trusty xinit' to your /home/chronos/user/.bashrc (in chromeOS shell).

   Check out these files for i3 configuration:

   • config
   • i3status.conf
   • i3lock.sh
   • i3exit.sh

   Note that before using those files, you need to install scrot and imagemagick (e.g., by using apt-get).

6. Install Dropbox.

   cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
   ~/.dropbox-dist/dropboxd
   

7. Install Zotero

   • Download from here
   • Extract to a desired position
   • Add that path into PATH by adding PATH="/path/to/zotero:$PATH" (Note there is no forward slash after zotero)

8. Install TiddlyDesktop

   • Download from here (I prefer v0.0.3)

   • Extract to a desired position

   • Add that path into PATH by adding PATH="/path/to/tiddlydesktop:$PATH"

   • In case of "nothing happens" (From: https://github.com/Jermolene/TiddlyDesktop):

     1. Install the package "bless" sudo apt-get install bless
     2. Load bless
     3. open nw file
     4. Search for "udev.so.0" and replace with "udev.so.1" -- set both fields to text
     5. save.

9. Install TexLive Full after installing ubuntu

   sudo apt-get install texlive-full
   

Configure other settings and have fun!

Later maintenance

2. Backup

   sudo edit-chroot -b nameofchroot

   cd /usr/local/chroots && sudo delete-chroot -y * && rm -rf /usr/local/bin
   

Crouton instructions

Example installing trusty unity-desktop

 sudo sh ~/Downloads/crouton -r trusty -a amd64 -t unity-desktop -e

run sh ~/Downloads/crouton to see the meaning of the options

usual targets: unity-desktop kde-desktop xiwi chrome

Update installed chroots

sudo sh ~/Downloads/crouton -u -n trusty -e

Backup installed chroots

Use sudo edit-chroot -b nameofchroot (in a crosh terminal shell) to back up your chroot, and sudo edit-chroot -r nameofchroot to restore it. edit-chroot will warn you if you’re clobbering a chroot by restoring, in which case you need to run sudo edit-chroot -rr nameofchroot (two r’s to confirm that you want to clobber it). See https://github.com/dnschneid/crouton/wiki/Backups for more details.

How do I remove crouton? (I want to make a fresh install)

From: dnschneid/crouton#10

Yep. It's probably easiest to let crouton do the checking for you, through:

cd /usr/local/chroots && sudo delete-chroot -y * && rm -rf /usr/local/bin

but if you're curious, you can confirm there are no lingering bind mounts via

mount | grep '/usr/local/chroots/'

Use/Disable Xiwi

You can set the default method back to xorg by updating with the xorg target explicitly, after which you can still use xiwi via -X (e.g.: sudo startxfce4 -X xiwi).

Running individual applications in windows and tabs

With xiwi installed, you do not need a desktop environment. You can launch apps on an individual basis in a Chromium OS window or tab.

Enter your chroot to get a command line: sudo enter-chroot Launch your app via the xiwi command: xiwi app Use xiwi -T app to launch in a tab, or xiwi -F app to launch full-screen. You can combine those into a single command sudo enter-chroot xiwi -T app. You can silence output and run the command in the background via sudo enter-chroot -b xiwi -T app.

Language Support

This is really important to correctly display chinese!

From: https://github.com/dnschneid/crouton/wiki/Languages

1. Install language packs:
2. Base language packs:

sudo apt-get install language-pack-{language-code}

For Chinese Simplified, {language-code} would be zh-hans! (Unlike zh_CN used in locale.)

2. GNOME language pack (GNOME shell, Cinnamon, and Unity):

sudo apt-get install language-pack-gnome-{language-code}

3. KDE language pack (KDE):

sudo apt-get install language-pack-kde-{language-code}

4. Libreoffice

sudo apt-get install libreoffice-l10n-{language-code}

Here {language-code} would be zh-cn! (Unlike zh-hans used previously.)

2. Change the default language:

sudo update-locale LANG="{locale}" LANGUAGE="{language-code}:en"

Example: (when you want to use Simplified Chinese as default language) sudo update-locale LANG="zh_CN.UTF-8" LANGUAGE="zh:en"

Example: (when you want to use English-US as default language) sudo update-locale LANG="en_US.UTF-8" LANGUAGE="en:en"

Restart to take effect!
